WIRE-NAIL SHINGLE-CLAMP.

Specification of Letters Patent.

Patented Got. 28, 1919.

To all whom t may concern:

Be it known that I, ALBERT ABBE GRrs woLD, a-citizen of the United States, resid` ing at Providence, dence and State of vented Wireail Shingle-Clamps,'of whlch the following is a specification..

My invention has reference to an 1mprovement in means for securing shingles to roofs and the like, and more particularly to an improved combined wire-nail and shingle clamp for fastening down the otherwise free end of flexible shingles, in shingling a roof or the like, with flexible shingles.

In thef'cons'truction of roofs and the like Rhode Island, have inyon which flexible shingles are used, it is necessary to hold down the free endsof the shingles so as to prevent bending or curling up of the shingles, thereby giving an unsightly appearance and allowing rain, snow or sleet to beat up under the shingles.

The object of my invention is to improve the construction of a, combined wire-nail 'and shingle clamp whereby in driving the nail, the end of a flexible shingle is simultaneously clamped down in place and the upper end. of a shingle previously laid is nailed downff'fin one operation.

invention consists in the peculiar and novel construction of a `wire-nail shingle clamp formed integral` of wire and so constructed as to clamp down Ia bent under flap on the outer end of a flexible shingle, and to nail' dewn the upper end of a shingle previously laid, in driving the nail portion of theclamp, said wire-nail shingle clamp having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1, is a face View of a portion of a flexible shingled roof showing the fla on one of the shingles clamped down an the upper end of a shingle previously laid, nailed down, Iby one of my improved wirenail shingle clamps.

Fig. 2 is an enlarged face view of my improved wire-nail shingle clamp showing the same in position for clamping down the bent under flap of a flexible shingle.

Fig. 3 is' an enlarged side view of the wire-nail shingle clamp showing the same in the county of Provia new and useful Improvement inl clamping down the bent under flexible shingle, and

ig. 4 is an enlarged perspective view of the wire-nail shingle clamp.

In the drawing 5. indicates the boarding of a roof, 6.6 flexible shingles, and 7.7 my improved wire-nail shingle clamps. The roof'boarding 5 may also represent the boardingon the outer walls of a building.

he flexible shingles 6.6 may be constructed of paper, tar and gravel or other flexible composition or fibrous material. Each shingle 6 has its outer end or corner bent under and formed into a flap 8, as shown in Figs. 1, 2 and 3.

My wire nail shingle clamp 7 is constructed to have a straight body portion 9, on one end of which is a downwardly bent wire-nail member 10 having a pointed end 11 and on the other end of the body portion 9 a clamping member 12 bent sidewise from the body portion 9, all formed integral of wire, as shown in Fig. 4.

In using my improved wire-nail shingle clamp in shingling a roof or the like with flexible shingles 6.6, the shingles 6.6 are laid diagonally, each shingle in a course bein first laid with the underside'outward an the flap 8 pointing upward. A wire-nail shingle clamp 7 is now placed over the flap 8 on the shingle in a position to bring the clamping member 12 centrally across the flap 8 adjacent the bend in the flap and with the wire-nail pointing downward above the flap 8, and on to the upper end of a shingle previously laid. The wire-nail member l0 is then driven through the upper end of the previously laid shingle inthe lower course and into the roof boards 5.5, thereby clam ing down the flap 8 on the shingle and'nall- Aing down the upper end of the previously laid shingle. The shingle being laid is then bent up over the wire-nail shingle clamp, as shown in heavy dotted lines in Fig. l and laid flat on the roof, face outward, and the shingling continued, the shingles being laid in each course as described.

By the use of my improved wire-nail shingle clamp the flap 8 on a shingle down and the upper end of a operation,

flap of a'( therefore, only one Wire -nail shingle clamp and only one operation is required for clamping down the flap on the outer end oi a shingle -and nailing a shingle in place.

I do not Wish to confine myself to the construction shown, as the shape of the Wirenail shingle clamp could be modified and the' material used varied, Within the scope of the appended claims.

Having thus described my invention, I1

claim -as new The combination with the boarding of a building of a flexible shingle having a turned under iap, a Wire-nail shingle clamp-- having a straight body portion, on one end of which is a downwardly bent Wire-nail member having Aa pointed end adapted to be driven into the boarding, and on the other end of, the body portion a clamping member bent sidewise and at right angles to the wire-nail member and adapted to lie flat on,

, the turned under lap on the flexible shingle,

whereby the turned under lap of the shingle is clamped in place on the boarding yand the shingle clamp is concealed and protected by `the shinglevvhen. said nail member is driven to position. f

In testimony Wh reef I have signed my name to this specification.

ALBERT ABBE GRISWOLD.
